Customer Satisfaction

Customer Satisfaction has been a very big priority for us since VNWA was first launched in 2008!!

Download and t ry out the DG8SAQ VNWA Software first before ordering. The VNWA software will start up without the VNWA hardware connected. This allows you to check-out the VNWA features and functionality and assess whether a purchase will meet your expectations.

Every effort is made to make the VNWA easy and intuitive to use for new owners, but be prepared to "invest some time" to get familiar with the many uses and options of the VNWA 3 or 3E!!

Take a look at the latest version of the 300+ page VNWA PDF helpfile link: http://sdr-kits.net/DG8SAQ/VNWA/VNWA_HELP.pdf

Ongoing support of all our VNWA Customers

General Software updates for the VNWA 3 and the VNWA 3E are made available several times a year. The same Software release is used to add new functionality to the VNWA 3 but also to the older VNWA 2.x if this can be supported by the VNWA 2.x hardware.
